I just got this new little cave decoration for my betta's aquarium because I thought he needed more of a 'hiding space' than the plants he has in their now. As soon as I put it in a few minutes later he started to flare up! This is the first time I've ever seen him flare so it was surprising. Its a few hours later now and he is still flaring up and acting aggressive. Is this because of the new cave ornament?
I have a 1.5 gal tank right now so it maybe it seems a little crowded for him maybe, but I ordered a 3 gal tank a few days ago from the Foster and Smith website so that should come any day now so hopefully he will be happier.
